For example, if there’s some trouble connecting due to networking problems or excessive load requests from customers present on the server’s side, that might result in a resolution-related delay causing a subsequent timeout problem. Modifying this setting does affect performance.

When this data block is read, it decompresses it in memory and presents it to the incoming request. When data is written to disk, MongoDB compresses it with a specified block compression method and then writes it to disk. Block compression can improve performance by allowing data to be read and written in smaller chunks.

This means that, if the Cache-Control: max-age=60 header is still present, the cached file’s 60 seconds starts again. If there is a newer file available on the server, we definitely want to download it. If, however, there wasn’t a new file on the server, we’ll bring back a 304 header, no new file, but an entire roundtrip of latency.
